Hi AJS,
Rcord Quota (limiting the number of records per user) has been added in version 3.5.1, which also fixes an encoding issue for fields of type HTML Text, which has been discovered for UDT 3.5.0, therefore, if you are using HTML columns, please wait for 3.5.1
To install a new module version, download the package, login as superuser ("host"), go to Module definitions in Host menu and choose "Install New Module" command. browse for your local package file and click install. verify that there is no issue in the upgrade log.
